Default examples not working

[Zhenya]

When attempting to run the default examples, they all fail to compile. I get this error with the light example.
(this is only the last part of the error, as it is too big so i didnt paste it here)

Can you send full config? Which board is selected in Arduino IDE? Did you enable C++17 for Arduino IDE? What version of ESP32 boards are you using?

[Zhenya]

Here is my board config:

I believe enabling c++ is a windows feature, while im on mac, and what exactly do you mean by a version of a board?

[WillemJoosten]

Managed to get it to compile:
you MUST use the C++17 modification as mentioned in the readme.
I also struggled to get it to compile on my Mac (Ventura 13.6) but C++ is not a windows-only feature :)

@zhekch did you manage to solve this issue? As @WillemJoosten said, C++ is not a windows-only feature 😊
